Abstract

Procédé de production de pâte chimique à partir de matériau fibreux cellulosique pulvérisé, qui consiste à mettre en digestion le matériaux fibreux à l'aide d'un liquide de digestion sans passer par la phase préalable du peroxyde. Selon la présente invention, le matériaux fibreux pulvérisé subit une phase de traitement au moins avant la digestion, en présence d'un liquide contenant au moins un composé qui a la capacité de former des complexes avec des métaux naturellement présents dans le matériau fibreux.
